To provide a road condition determination device capable of determining a snow damage condition in a simple device configuration.SOLUTION: A road condition determination device 4 comprises: a data acquisition section 410 for acquiring road data including image data obtained by imaging a road of a determination target and a periphery thereof at a predetermined point and at a predetermined time; and a determination section 411 for determining a snow damage condition in the road of the determination target and the periphery thereof by inputting to learning models 403A-403D the image data of the determination target included in the road data acquired by the data acquisition section 410. For the learning models 403A-403D, machine learning is performed by a data set for learning consisting of image data, which are obtained by imaging a road of a learning target and a periphery thereof, and a correct answer label indicating a determination result of a snow damage condition in the road of the learning target and the periphery thereof.SELECTED DRAWING: Figure 9
【課題】簡易な装置構成で雪害状況を判定することを可能とする道路状況判定装置を提供する。【解決手段】道路状況判定装置4は、所定の地点及び時刻において判定対象の道路及びその周辺が撮影された画像データを含む道路データを取得するデータ取得部410と、データ取得部410により取得された道路データに含まれる判定対象の画像データを学習モデル403A~403Dに入力することにより、判定対象の道路及びその周辺の雪害状況を判定する判定部411とを備える。学習モデル403A~403Dは、学習対象の道路及びその周辺が撮影された画像データと、学習対象の道路及びその周辺の雪害状況の判定結果を示す正解ラベルとで構成される学習用データを複数含む学習用データセットにより機械学習が行われたものである。【選択図】 図9
